Last weekend I had to go to the trouble of restarting the Bauer 20V battery as it completely forgot how to turn on and work. No matter how long I left it on charge the battery wouldn’t recharge and turn on.
That’s where I knew my battery was asking for a restart and here is how I did it by using these 3 methods.
But before you continue reading about these 3 different methods, you could first watch my short video about this topic. You can watch it below.
On my video I demonstrated how to reset a Bauer 20V battery by using another similar Bauer battery, a battery from a different brand, and a DC power supply.
3 Simple Ways to Reset 20V Bauer Battery
Method 1: Reset Using Another Bauer Battery
1. If you have another Bauer battery laying around that works properly, you are in luck. Just make sure the voltage of the battery matches each other, you might not want to fry anything.
2. Luckily, I also had another Bauer battery laying around. I connected the positive terminal of the healthy battery to the positive of the dead Bauer battery and then did the same for the negative terminal.
I used the jumper wire cables to connect both the terminals together.
3. I only kept both the batteries connected for 15 seconds which was enough to send a little jolt down the dead battery and revive it.
Method 2: Reset Using a Different Brand of Battery
1. Since not everyone will have the same Bauer battery, here is how you can use a battery of different brands to reset your Bauer battery and get it to charge again.
2. I first identified + and – terminals on both the batteries and hooked them together using jumper wires. Remember to hook the terminals correctly and not mix them, otherwise you will end up frying your battery.
3. Then I left both the batteries connected for at least 15 seconds, this generated enough burst of energy in the dead battery to be charged back up again and work normally.
If you follow these steps your battery will also come back to life again.
Method 3: Reset Using a DC Power Supply
1. A DC power supply can do wonders, at least it did for me when it helped me revive my Bauer battery. If you also have a DC power supply at home you are in luck.
2. I started with setting my power supply voltage to 20V and 1A, matching the output of my battery. Don’t crank it higher, you might end up damaging the cells.
Then I hooked the battery to the power supply by connecting its positive terminals to positive and negative to negative.
3. Leave them hooked up for 15 seconds, then disconnect it. This generated enough voltage in my Bauer battery to be charged again and the charger showed me the green light I was looking for.
And speaking of lights on your Bauer battery charger, I also made a short video about this topic. You can watch it below.
If you see a solid green + flashing red, it means the battery is charging. A solid red and green means charging is complete. A flashing red only means a hot or cold delay and a flashing red and green indicates a bad battery.
